Rock Falls In Yosemite National Park, the Video!

Published Date

July 11, 2010

Rock falls are part of life in the Yosemite Valley, as this video from Yosemite Nature Notes explains. NPS graphic of rock falls in the valley.

Despite the towering walls of granite that rim the Yosemite Valley in the heart of Yosemite National Park, the place is decidedly not static. Rather, it's a constantly evolving geologic entity that is both deadly and mesmerizing.

According to the geologists at Yosemite, "(R)ock falls are a natural and dynamic geologic process. Due to its steep, glacier-carved cliffs, Yosemite Valley experiences many rock falls each year. Historical records indicate that at least 600 rock falls have occurred in the park during the past 150 years. Massive piles of 'talus' or rock debris at the base of Yosemite Valley’s cliffs are reminders of these dramatic events. Natural processes like rock fall help to create the beautiful and changing scenery in Yosemite National Park, but they also present potential hazards."

In his latest production for Yosemite Nature Notes, videographer Steven M. Bumgardner has put together a great video that explains how, since the disappearance of glaciers about 15,000 years ago, rock falls have become the greatest erosional factor in the continued sculpting of Yosemite Valley.

Support National Parks Traveler

Your support for the National Parks Traveler comes at a time when news organizations are finding it hard, if not impossible, to stay in business. Traveler's work is vital. For nearly two decades we've provided essential coverage of national parks and protected areas. With the Trump administration’s determination to downsize the federal government, and Interior Secretary Doug Burgum’s approach to public lands focused on energy exploration, it’s clear the Traveler will have much to cover in the months and years ahead. We know of no other news organization that provides such broad coverage of national parks and protected areas on a daily basis. Your support is greatly appreciated.

Is there any more to this article? I'm not seeing anything except one short paragraph, even when I click on "read more." The paragraph reads as if there should be a video. I'd love to see it if there is.

Never mind. The whole article showed up after I clicked send my comment.

But there's something wrong with the links that wouldn't let me get to the whole article before I commented. Just so you know.

Meg,

My guess is that the download took a little while, and until it loaded there was nothing to see.

Glad it showed up!
